HENRY F. CRANDALL, OF MIIVAUKEE, \VISCONSIN, ASSIGNOR TO THE MIL- TAFKEE HARVESTER COMPANY, OF SAME PLACE.

HARVESTER.

SPECIFICATION forming part of Letters Patent No. 407,063, dated July 16, 1889.

Application filed September 6, 1887. Serial No. 248,938. (No model.)

To [oli whom it 77mg/ concern.-

Be it known that I, HENRY F. CRANDALL, of Milwaukee, in thc county of Milwaukee, and in the State of Il'isconsin, have invented certain new and useful Improvements in I'Iarvesters; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to harvesters, and will ro be fully described hereinafter.

In the drawings, Figure l is an elevation of the rear end of a harvester embodying my invention. Figs. 2 and 3 are detached elevations of my invention. Fig. ai is a longitudinal section of the same. Fig. 5 is a section on line c 4r, Fig. 3. Fig. G is a detail. Fig. is a plan View of a harvester embodying my in vention. Figs. 8 and 9 are details.

A is the harvester-frame, and A the grain- 2o platform.

I3 is the bull-wheel, which turns loosely on its axle P, which latter carries a pinion p on each of its ends, each of which is for engagement with a curved rack c, that is carried by the harvester-frame. On one end of axle P, between the pinion on that end and the bullwheel, a sheave C is keyed to the axle and a cable D is secured at one end to the sheave, while its other end, after passing under auother sheave h, that is attached to the lower end of the harvester-frame, extends up to a sleeve E, that has its bearings at c c on a shaft F, that in turn has its bearings at each end on the rear upper portion of the harvesterframe.

The sleeve E is formed with a flange on its surface, so as to make two sheaves d and e, the sheave d to take the rope or chain D, which lies in the spiral groove j' and is secured to the sheave at g, and the sheave e to receive a rope or chain h', one end of which is attached to the sleeve at 72, and passing in a spiral groove i over onto sheave e, and from thence down to a sheave 7,, is led out around a sheavem on the rear outer corner of the harvester-platform to the lifting mechanism M on the outer end of the platform, which maybe of any well-known and usual construction. This mechanism forms no part of my invention and may be of any approved construction. Near its farthest end from sheave (l the sleeve E is provided with a hooked lug or pin n, and keyed to F and abutting sleeve E is another sleeve G, which is formed or otherwise provided with a lug or pin o, the lugs n ando heilig` similar to each other but facing in opposite directions, and these lugs each anchor one end of a spiral spring Il, which surrounds the adjacent ends of the sleeves G and E and joins the two, so that when the shaft F is turned the 6o sleeve G, which turns with it, will also, through spring II, turn the sleeve E, and, as the harvester is suspended by ropes or chains D and h from the sleeve E, its weight will be supported by the sleeve G through the spring H.

The operation of my device is as follows: When the machine is to be raised or lowered, the shaft F is revolved by means of a lever j and its ratchet-wheel J, and, acting through sleeve G and spring Il, will revolve the sleeve 7o E to wind up the ropes or chains D b', the spring II yielding sufciently to prevent shock and consequent strain on the frame, and the spring H also forming an elastic support for the machine as it is Working.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, in a harvester, of a b ull-wheel, its axle, and the pinions and sheave 8o carried by the axle, with racks fixed to the harvester-frame and receiving the pinions, a lifting-shaft carried by the h arvester-f rame, a fixed and loose sleeve carried by the shaft, a spring uniting' the two sleeves, and a flexible 8 5 connection having one end secured to the sheave and the other to the loose sleeve, substantially as described.

The combination, with the lifting-shaft and its fixed and loose sleeves and uniting- 9o spring, of a flexible connection having one end secured to the loose sleeve and the other end secured to an arm of the lifting mechanism for the outer end of the grain-platform, substantially as described.

3. The combination, in a harvester, of a bull-wheel, its axle and pinions, a sheave carried by the axle, racks fixed to the harvesterframe and receiving the pinions, a liftingshaft carried by the harvester-fraine, a fixed roo and looseA sleeve carried by the shaft, a. spring In testimony that I lClaim the foregoing I uniting the two sleeves, ordinary lifting meohhave hereunto set my hand, at Milwaukee, in to anism on the axle of the grain-wheel, and the county of lMilwaukee and State of WisfleXible Connections leading from the loose cousin, in the presence of two witnesses.
